Abstract
A process for the production of sodium hydroxide, hydrogen gas and chlorine gas which comprises (1) forming an aqueous solution of sodium chloride, (2) placing the sodium chloride solution in a cell having two compartments separated by a separator, (3) subjecting the cell to a direct electrical current of about 3-24 volts and 0.1-500 K amperes; thereby generating hydrogen gas, chlorine gas and an aqueous sodium hydroxide solution and wherein the electrical current is generated by a solar panel.
